Background
Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined.
Methods
This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months.
Conclusion
This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Background

Type 2 diabetes is one of the most common diseases with devastating complications. However, genetic susceptibility of diabetic complications has not been clarified. The vitamin D endocrine system is related with calcification and lipolysis, insulin secretion, and may be associated with many complicated disease including diabetes and cardiovascular disease. Recent studies reported that single nucleotide polymorphisms of vitamin D receptor (VDR) gene were associated with diabetic complications.

Methods

In present study, we evaluated the association of BsmI polymorphism of VDR with diabetic complications in Korean diabetes patients. Total of 537 type 2 diabetic subjects from the Endocrinology Clinic of Chungbuk National University Hospital were investigated. Polymerase chain reaction-restriction fragment length polymorphism was used to test the genotype and allele frequency of BsmI (rs1544410; BB, Bb, bb) polymorphisms.

Results

Mean age was 62.44±10.64 years and mean disease duration was 13.65±7.39 years. Patients with B allele (BB or Bb) was significantly associated with lower risk of diabetic retinopathy (severe non-proliferative diabetic retinopathy or proliferative retinopathy; 7.4%, 5/68) compared with patients without B allele (bb; 17.3%, 81/469; P=0.035). This association was also significant after adjusting for hemoglobin A1c level, body mass index, age, sex, and diabetes mellitus duration, concurrent dyslipidemia and hypertension (odds ratio, 2.99; 95% confidence interval, 1.08 to 8.29; P=0.035) in logistic regression analysis.

Conclusion

Our findings suggest that B allele of Bsm1 polymorphism in VDR gene is associated with lower risk of diabetic retinopathy in type 2 diabetic patients. Bsm1 genotype could be used as a susceptibility marker to predict the risk of diabetes complication.

Abstract PDF: A lingual thyroid is a rare developmental anomaly caused by the failure of the descent of the thyroid gland anlage early in the course of embryogenesis. The incidence of lingual thyroid has been reported to be 1/100,000. Lingual thyroid is often asymptomatic but may cause dysphagia, dysphonia, upper airway obstruction and hemorrhage. In this report, we described the case of a 50-year-old women experiencing lingual thyroid who had subclinical hypothyroidism. She underwent successful 131I ablation and has done well on thyroid hormone replacement therapy.

Abstract PDF: Developing Cushing's syndrome during pregnancy is rare because menstruation is irregular and hypercortisolism causes infertility. Developing Cushing's disease during pregnancy is very rare because there is even less ovulation than those with the adrenal adenoma. The clinical manifestations of Cushing's syndrome may easily be missed during pregnancy as the features of weight gain, hypertension, and hyperglycemia overlap with those that occur during a pregnancy. Diagnosing Cushing's syndrome during a pregnancy is complex because the biochemical features are obscured by the natural changes in the hypothalamic-pituitary-adrenal axis that occur during pregnancy. Having Cushing's syndrome during a pregnancy results in increased fetal and maternal complications, so early diagnosis and treatment are critical. We report the clinical and endocrine findings of a pregnant women with Cushing's disease who underwent transsphenoidal surgery after delivery.
